SpecifmationI forming part of `Letters Patent No. 115,443, dated May 30, 1871.

I, JOHN G. CURTIS, of `iarremin the county of Warren and State of Pennsylvania, have invented certain Improvements in Machines for Rolling SolelLeather, of which the following is a specification:

Nature and Object of-my Invention.

My invention relates to pressing the leather when between the roller-bed and roller, the roller being in motion. To make it solid and firm it is worked with treadle and rock-shaft,`

forcing the' roller-bed up against the roller; and -is an improvement on my patent No. 101,234, dated March 29, `1870. C

Description of thcAccompanyng Drawing.

Figure 1 isa side elevation of mymachine. Fig. 2 isa transverse section through the rod y operated by therock-shait arm.

`Similar'letters refer to corresponding parts.

A is the frame of the machine. B is the pendent vibrating supportfor the roller.' C is the roller. 4 D is `the roller-bed. E is the connecting-rod, bywhich motion is communicated to the roller; F,`.p1ank which supports the roller-bed G, rollers placed in pairs on short shafts, one over the other, and held in place by the bearing-blocksK; H, connecting-rod, connectin gblocks KWith rock-shaft arm J. L is treadle.

y I are wedgeshaped blocks,forming a track quick when the foot for the rollers G, with a ange on each side to guide said rollers.

The machine is Worked by placingthe foot on the treadle and forcing it down, which. forces the rollers underv the roller-bed up the inclined planes I, raising the roller-bed, and

' pressing the leather against th'e roller with The combinations of the rollersG with the bearing-blocks K and wedged blocks I, forming a track for said rollers G, for the purpose herein described.
